Managing Agricultural Greenhouse Gases Network (MAGGnet): Exploring Greenhouse Gas Mitigation Potential of Cropland Management Practices.

Greenhouse gas research networks provide a framework for the systematic testing of theories by multiple scientists across international borders.  In 2012, a greenhouse gas research network referred to as MAGGnet (Managing Agricultural Greenhouse Gases network) was established within the Global Research Alliance Croplands Research Group.  With involvement from 46 alliance member countries, MAGGnet seeks to provide a metadata platform for the inventory and analysis of cropland greenhouse gas mitigation research throughout the world.  Using a standardized spreadsheet template, metadata from over 300 experimental sites in 20 countries were compiled, and sites with published data for soil organic carbon, greenhouse gas flux, and crop yield were identified.  Data for these response metrics will be analyzed to quantify the effectiveness of common mitigation practices and assess potential tradeoffs in greenhouse gas mitigation and crop yield.
